Description

Technical Field

[0001] This utility model relates to the field of masking tray technology for arc spraying, and more specifically to a masking tray assembly for arc spraying. Background Technology

[0002] Arc spraying is a widely used technique for metal surface treatment. Its main characteristic is the generation of an electric arc between two conductive wires to melt the wires, which are then atomized into tiny droplets using compressed air and sprayed onto the target surface to form a coating. During arc spraying, to ensure a uniform coating and prevent contamination of non-target areas, masking materials are typically used to protect these areas.

[0003] Existing methods for arc spraying masking typically involve applying tape to areas that do not require spraying before the spraying process. This method places significant demands on the quality of the tape, and since the tray is usually fixed in place, over time, a large amount of spray particles may accumulate, resulting in inaccurate spraying of the workpiece placed on it and affecting processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a masking tray assembly for arc spraying in order to solve the above problems. By using a detachable and washable limiting spraying mechanism and a sponge absorption layer, the amount of tape used is reduced, and the tray mechanism is protected, making the spraying range of the workpiece more accurate.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A masking tray assembly for arc spraying includes: a tray mechanism, a masking mechanism snapped onto the top side of the tray mechanism, a limiting spraying mechanism extending through the inner side of the masking mechanism, a sponge absorbent layer fixedly disposed on the bottom side of the limiting spraying mechanism, and multiple bolts disposed on one side of the masking mechanism near the top.

[0007] The shielding mechanism includes a slotted frame, with a first transverse slot and a second transverse slot respectively opened on both sides of the inner wall of the slotted frame, an opening plate fixedly installed on one side of the slotted frame near the top, an inclined surface provided on the inner wall of the slotted frame near the top, and a snap-fit ​​groove opened on the bottom side of the slotted frame.

[0008] Furthermore, the limiting spraying mechanism includes a limiting spraying plate, a first clamping plate is snapped onto one side of the limiting spraying plate, and a limiting plate is fixedly provided on one side of the first clamping plate.

[0009] Furthermore, a second clamping plate is fixedly provided on the side of the limiting spraying plate away from the first clamping plate, and front and rear clamping plates are fixedly provided on both the front and rear sides of the second clamping plate. The front and rear clamping plates are formed by joining two L-shaped plates together, and the right angle of the L-shape faces the bottom side of the limiting spraying plate.

[0010] Furthermore, a connecting plate is fixedly provided on one side of the second clamping plate, and multiple fixing holes are opened on the top side of the connecting plate, and the bolt passes through the opening plate and the fixing holes.

[0011] Furthermore, the surface of the sponge absorbent layer has holes corresponding to the limiting spray plate, and the sponge absorbent layer is disposed on the bottom side of the limiting spray plate.

[0012] Furthermore, the pallet mechanism includes a pallet base plate, a snap-fit ​​plate is fixedly provided on the outer side of the top side of the pallet base plate, and a limit plate is provided on the inner side of the snap-fit ​​plate on the top side of the pallet base plate.

[0013] Furthermore, the snap-fit ​​plate is snap-fitted inside the snap-fit ​​groove.

[0014] Furthermore, the holes in the limiting base plate, the sponge absorption layer, and the limiting spray plate are all correspondingly configured.

[0015] In summary, the beneficial effects of this utility model are as follows: by making the limiting spraying mechanism and the sponge absorption layer reusable, the usage cost is reduced and the service life is increased. The connection between the masking mechanism and the limiting spraying mechanism is also very convenient, which improves the ease of installation and disassembly of the limiting spraying mechanism. In addition, it protects the tray mechanism, avoids the accumulation of too much spray liquid in the tray mechanism, and prevents the workpiece from being placed at an inconsistent height, thereby improving the accuracy of spraying.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] See Figures 1-7 As shown, this utility model provides a masking tray assembly for arc spraying, including: a tray mechanism 1, a masking mechanism 2 snapped onto the top side of the tray mechanism 1, a limiting spraying mechanism 3 penetrating through the inner side of the masking mechanism 2, a sponge absorbent layer 4 fixedly disposed on the bottom side of the limiting spraying mechanism 3, and multiple bolts 5 disposed on one side of the masking mechanism 2 near the top.

[0029] Using the above technical solution, the tray mechanism 1 provides a base and support for the sprayed part, and the masking mechanism 2 works in conjunction with the limiting spraying mechanism 3 and the sponge absorption layer 4. During the spraying process, the masking mechanism 2 and the limiting spraying mechanism 3 block the directly sprayed liquid particles, and then the sponge absorption layer 4 absorbs any spray liquid that may seep in, avoiding the residue of spray liquid in the tray mechanism 1. The masking mechanism 2 and the limiting spraying mechanism 3 are connected and fixed by bolts 5, so that the two structures are fixed to each other, which facilitates the stability of the workpiece to be sprayed.

[0030] See Figures 5-8 As shown, the shielding mechanism 2 includes a slotted frame 201. The inner walls of the slotted frame 201 are respectively provided with a first transverse slot 202 and a second transverse slot 203. An opening plate 204 is fixedly provided on one side of the slotted frame 201 near the top. An inclined surface 205 is provided on the inner wall of the slotted frame 201 near the top. A snap-fit ​​groove 206 is provided on the bottom side of the slotted frame 201.

[0031] During use, the slotted frame 201, through the inclined surfaces 205 around its inner wall, increases the contact surface between the workpiece to be sprayed and the spraying angle during the spraying process. At the same time, the inclined surfaces 205 also make cleaning easier when not in use. The perforated plate 204 corresponds to the fixing hole 307 in the limiting spraying mechanism 3, and can be connected together using bolts 5. The snap-fit ​​groove 206 is used to cooperate with the snap-fit ​​plate 102 in the pallet mechanism 1, so that the pallet mechanism 1 and the masking mechanism 2 can be quickly connected. When disassembling, since the outer surface of the pallet mechanism 1 is rounded and the masking mechanism 2 is right-angled, it provides workers with operating space to quickly remove the masking mechanism 2.

[0032] See Figure 5 and Figure 6 As shown, the limiting spraying mechanism 3 includes a limiting spraying plate 301. A first clamping plate 302 is snapped onto one side of the limiting spraying plate 301. A limiting plate 303 is fixedly installed on one side of the first clamping plate 302. A second clamping plate 304 is fixedly installed on the side of the limiting spraying plate 301 away from the first clamping plate 302. Front and rear clamping plates 305 are fixedly installed on both the front and rear sides of the second clamping plate 304. The front and rear clamping plates 305 are formed by joining two L-shaped plates together, with the right angle of the L-shape facing the bottom side of the limiting spraying plate 301. A connecting plate 306 is fixedly installed on one side of the second clamping plate 304. Multiple fixing holes 307 are opened on the top side of the connecting plate 306. The bolt 5 passes through the perforated plate 204 and the fixing holes 307. The surface of the sponge absorbent layer 4 has holes corresponding to the limiting spraying plate 301, and the sponge absorbent layer 4 is located on the bottom side of the limiting spraying plate 301.

[0033] In the above embodiment, the limiting spray plate 301 is clamped by the first clamping plate 302 and the second clamping plate 304. The position of the limiting spray plate 301 in the masking mechanism 2 is adjusted by the limiting plate 303 on one side of the first clamping plate 302. The second clamping plate 304 lifts the entire limiting spray plate 301 from the bottom and front and rear sides by the front and rear clamping plates 305. Together with the first clamping plate 302, the limiting spray plate 301 is in a higher position in the masking mechanism, providing space for the sponge absorption layer 4. The multiple fixing holes 307 on one side of the connecting plate 306 correspond to the holes in the perforated plate 204. The two can be connected together by bolts 5. When the installation is completed and during the spraying process, after the liquid particles seep from the limiting spray plate 301, they are directly absorbed by the sponge absorption layer 4, preventing the sprayed particles from directly contacting the tray mechanism 1.

[0034] See Figure 7 and Figure 8 As shown, the pallet mechanism 1 includes a pallet base plate 101. A snap-fit ​​plate 102 is fixedly provided on the outer side of the top side of the pallet base plate 101. A limiting base plate 103 is provided on the inner side of the snap-fit ​​plate 102 on the top side of the pallet base plate 101. The snap-fit ​​plate 102 is snapped into the snap-fit ​​groove 206. The holes in the limiting base plate 103, the sponge absorption layer 4, and the limiting spray plate 301 are all correspondingly provided.

[0035] In use, the pallet bottom plate 101 is usually fixed in one position. When spraying is required, the snap-fit ​​plate 102 on the top side of the pallet bottom plate 101 directly contacts and snaps into the snap-fit ​​groove 206 in the masking mechanism 2, snapping the masking mechanism 2 into the top of the pallet mechanism 1, and masking the limiting bottom plate 103 in the pallet mechanism 1. This prevents spray particles from being sprayed directly onto the pallet bottom plate 101, causing uneven height of the holes in the limiting bottom plate 103 due to the accumulation of spray particles, thus affecting the spraying effect.

[0036] Using the above structure, when spraying the workpiece, firstly, the limiting spraying mechanism 3 with the sponge absorption layer 4 is inserted through the first transverse groove 202, inserted into the masking mechanism 2, and protrudes from the second transverse groove 203. Then, the snap-fit ​​groove 206 is aligned with the snap-fit ​​plate 102 in the tray mechanism 1, and the masking mechanism 2 is fastened above the tray mechanism 1. Then, the bolt 5 is inserted through the opening plate 204 of the masking mechanism 2 and the fixing hole 307 of the limiting spraying mechanism 3 to connect the masking mechanism 2 and the limiting spraying mechanism 3 together, ensuring the stability of the workpiece to be processed during the spraying process. At this time, the workpiece to be processed is inserted into the hole opened on the limiting spraying plate 301 in the limiting spraying mechanism 3, and then sprayed at the angle of the masking mechanism 2.

[0037] After the spraying is completed and dried, the masking mechanism 2 is first removed from the tray mechanism 1. Then, the masking mechanism 2 is inverted to quickly remove the dried workpiece. The cleanliness of the surface of the limiting spraying mechanism 3 is then checked by the worker to determine whether cleaning is required. If cleaning is required, the bolts 5 are removed from the perforated plate 204 and the fixing hole 307. At this time, the entire limiting spraying mechanism 3, along with the sponge absorption layer 4, can be pulled out from the masking mechanism 2 for cleaning. After the limiting spraying mechanism 3 is pulled out from the masking mechanism 2, the masking mechanism 2 is also easier to clean, thus improving its service life.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
